A three-way tie. Each player wound up with $16,000 so they all come back on Monday.
As noted, there was a three-way tie before but it was a matter of everyone wiping out. This is, I guess, the first three-way tie where everyone won money. That's what all the fuss was about. And I guess the Game Theory person suggested that it would never happen again because now that the possibility of a three-way tie has entered into the way Jeopardy! contestants figure when they wager, they'll henceforth bet to make that less likely. Or something of the sort.
